Giant Asian hornets have now migrated to Washington state and British Columbia.  Even though they are sometimes called "murder hornets" their stings aren't fatal.  Their stings are brutal though and they are huge. How big do you think one of these hornets really is?  Can you draw it to scale on a grid? Should we all buy protective suits?  How many do you guess are in one nest? Find out more.
